Oxidative Stress and Preventive Measures
Oxidative stress causes many human diseases. Severe diseases are often preceded by rapid changes in all the internal organs of the body. One reason for these changes is the destructive action of free radicals. When there is excess amount of free radicals, they cause an oxidative stress in the body.
We've already talked about what free radicals are, and how they are formed in the body.
Effects of Oxidative Stress on the Body
In recent years, many experts have pointed to the imbalance between the protective function of the antioxidant system and the emergence of free radicals in the body. Free radicals are not formed in just one particular organ; they are formed throughout the body. Often, a human body is unable to deal with a large number of free radicals that are by-products of the normal functioning of the body.
Oxidative stress disrupts the structure of the cells, affects the genes that cause aging, and change and cause the degradation of the internal organs. Increased oxidative stress causes an accumulation of various metals, e.g. copper, iron, or lead. These metals react with free radicals and weaken body’s antioxidant defense system. A variety of substances of plant origin can help resist oxidative stress and help reducing the concentration of the free radicals in the body. In other words, these substances bind free radicals and transform them into neutral particles. In addition, there are antioxidants, which stimulate the antioxidant defense system of the body.
What You Have to Eat
Don’t leave your body exposed to any severe diseases. Every person can maintain good health - it is not hard at all. As you know, the food you eat directly affects your health. The substances that combat oxidative stress can be found in foods. Most fruits and vegetables contain antioxidants.
Blueberries, cranberries, currants, raspberries, and strawberries are all fruits that should be included in any person’s diet. Everyone should eat these fruits to fight oxidative stress, which affects both healthy and sick people.
Cherries, pomegranates, plums, oranges, tangerines, lemons, grapefruits, grapes, apples, and apricots are just a fraction of fruits that are a delicious to eat. These products also provide our bodies with a sufficient amount of antioxidants and reduce the harm caused by oxidative stress.
For centuries, the human body has evolved to adapt to the foods that were necessary for its functioning. Mankind consumed what nature has given it in reasonable quantities. Not only do fruits and vegetables contain antioxidants, they also have many other useful properties too. In addition to their ‘cleaning’ function, they also have an ability to prevent oxidative stress.
It is, therefore, important to eat many vegetables.
Dietitians in different countries have come up withrecipes that contain many types of different foods. In addition to great flavor and taste, these recipes also have healing properties. They contain a range of vitamins, minerals, and other nutrients. Some vitamins such as vitamins A, C, E, and F are also powerful antioxidants themselves. This is why salads, vegetable mixes, and other multifaceted foods are always so popular. These dishes contain tomatoes, cabbage, onions, spinach, carrots, parsley, dill, and soy products.
In fact, you can include all of the popular vegetables used for cooking to this list. They contain vitamins, lycopene, flavonoids, and other complex components that are easily absorbed by the body and actively fight oxidative stress. All these substances are antioxidants. Many vegetables and fruits, which are consumed in everyday life, should be supplemented with a healthy diet; they can also be consumed in virtually any quantity. You can enjoy tasty juicy foods and know that they are also working to protect your body from free radicals.
Synthetic antioxidants, which are used in treatment of serious diseases, have quite different properties. If the internal organs and the human circulatory system are severely affected by oxidative stress, an antioxidant therapy is often needed. If you experience this problem, take medications that your doctor prescribes based on the severity of your problem. These medications and supplements should never be taken by a healthy person. You should not use these drugs instead of fruits and vegetables, as they won’t help you to protect your body from oxidative stress.
